    Hi. I'm new to plowing and just bought a pick-up with a used plow. I am having trouble with the pump, but I can't find any markings as to what brand it is. I was told the plow is a Mayer, but I can't find any similar models in their parts list. Any ideas, anyone? :confused:

    That kind of looks like a elec/hydro unit that you could buy from Northern Tool or something. It also looks like it could be home made, I don't even recongnize that lift frame.

    Could be an Artic plow setup. They come out of Canada. Older looking. They had some parts very similiar to Meyers.

    The powerpack itself looks like it could be a Monarch or similiar self contained unit. Northern does sell them.

    Do you need parts? A good hydraulic shop or truck upfitter should be able to get parts as needed especially if they can pull a number off it.

    You could just switch to a different brand pump like a Fisher or Meyer E-60 to make parts more accesable. Would likely need the controls also. Post pics of the whole truck with the plow on. That may help to identify it better.

    Yes I believe it is a Meyer lift frame, just an older one. The pump as someone said could be from Norther tool. A JS Barnes pump, I don't see any lines for hydro turn, and the reservoir is really big. It looks like it could be a small lift body pump. I would just replace it with a pump of your chose. If $ matters you could get an older western cable cheap. I say cable pump because you have a convectional lift frame.

    Looks like an old Monarch unit. if it works run it. They're great units and parts are available. Try a lift gate or dumpbody repair shop for parts.

    I bought a truck years ago that had a lift gate on it and had the same type of pump.

    it looks like its homemade with the round tubing and the western lift arm or maybe that truck had central hydro's at some point but that is definately a monarch pump.what does the lower mount look like?

    Definitely a monarch I have one on a 79 Ford F350 and never had any problems with it I may have a manual I can scan if needed.

    Thanks for your help on this, gentlemen! It is definitely a Monarch unit (probably a M-304, judging from the company's technical drawings).

    Since you were on the nose finding what this unit was, maybe you have an idea as to the diagnosis for my little problem. Here are the symptoms:

    - Unable to lift piston(this is a one piston setup, no side-to-side) with plow on.
    - Piston raises normally when plow is off.( This should be a sign that my controls are working ok, right?)
    - Electrical motor spinning ok. I had it checked, and it does not seem to be showing any problems.
    - I changed the regular transmission oil for 80w90 oil and I can now raise the piston with the plow on, but it has a hard time getting all the way up. ( i know 80w90 should not be left in, it was only to diagnose what the problem might be.)

    I figure worn parts in the pump. Any other ideas? Anyone ever fix a pump on this type of unit?

    You can't repair that pump, you have to replace it. Pumps are readily available.

    IT is the pump itslef which is part of that power unit. As said no parts in it to rebuild. Take the powerpack apart, replace the pump and while you are in there flush the whole system out. There may be a screen filter on the pickup in the resevoir to clean as well.

    there could be an adjustment screw for the amount of pressure the pump will put out
